CO₂ Measurement in Fermentation Processes

Continuous CO2 Tracking for Fermentation Progress & Process Control CO2-525X

Fermentation processes across food, beverage, and biotechnology applications generate CO2 as a byproduct, and tracking its evolution provides a direct, real-time indicator of fermentation activity and progress. Continuous CO2 monitoring supports process control decisions and helps operators identify fermentation issues early.

The CO2-525X gives fermentation operators continuous, reliable CO2 measurement, supporting real-time process tracking across a range of fermentation applications.

  • Fermentation Tracking
  • Process Control
  • Off-Gas Monitoring
  • Continuous Online Monitoring

Why CO2 Process Monitoring Matters

CO2 evolution rate is one of the most direct indicators of fermentation activity, rising as fermentation progresses and tapering off as it nears completion. Continuous CO2 monitoring gives operators real-time visibility into fermentation status, supporting decisions on timing, troubleshooting stalled or sluggish fermentations, and confirming consistency across batches.

Where It's Used

  • Fermentation vessel off-gas monitoring tracking CO2 evolution throughout the fermentation cycle
  • Batch-to-batch consistency verification comparing CO2 profiles across production runs
  • Stalled fermentation troubleshooting identifying when CO2 evolution drops unexpectedly
  • Process endpoint determination supporting decisions on when fermentation is complete

Häufig gestellte Fragen

Trace oxygen measurement provides a direct indication of oxygen contamination or crossover into the hydrogen stream. Trending the oxygen concentration can help operators identify changes in electrolyser or purification system performance.

A common measurement point is the hydrogen product stream downstream of the electrolyser stack. Additional measurement points may be used before or after drying and purification equipment depending on the process design and monitoring objectives.

Alarm and control limits should be determined based on the electrolyser manufacturer’s specifications, process conditions, applicable standards, and the facility’s safety requirements rather than using a universal oxygen alarm value.
